' To all ivhom it may concerns ism and means which. are hereinafter described and claimed, and which are illus trated in the accompanying drawings, in whicl1- Figure 1 is a sideelevation of a manuresprei-ider as separated from its carrying wheels,and illustrating the particular combination of elcmcntsused in my said ratchetfeertl-mechanism. Figs 2, is a perspective view of my improved forward support for the wagon-body, and Fig; 3 is a plan view of the rack to which the front and rear wagon supports are attached and by which it is supported. Fig. 4 is a detail view of the hand-lever of the said ratchet-feed-mechanism, showing its socket-bearing for theforward endoi" the connecting-rod Fig. 5 is a detail view inperspective of the cam operated lever in the ratchetfeed-mechanism. Fig. 6 is an,enl arged detail view of the camdriven ratchet-feed n'iechanism.

Similar numbers refer to similar parts throughout the several views.

The box 20,015 my improved manure spreader 15 supported on cross-beams 36 whose ends rest on the parallel longitudinal timbers 35. The latter timbers are su ported by the cross-bars. 32 and 33 at t e rear which rest on the rear bolster of a Wagon A frame (not'shown), and bye cross-bar '29 at the front which rests on the front wagon bolster, but blocks 28 are placed between the bar 29 and the timbers 35 to space the latter away from the front bolster andv compensate forthe lesser height of said bolster. Short bracket-arms 30-30 extend inwardly from the bases ofthe'bloclrs 28 to assist n supporting the guides 31 thereon. Similar guides 34. are affixed to the rear cross-timbers 32 33, and. all such guides serve to form ways for the apron 27 to move thereover, said a ron being driven by sprocket-wheels (not s own) on the transverse shaft 17, and its front end running over idler sprockets 26 at the front of the box 20. By the use of the supporting frame thus composed, the wagon-- box 20 can be placed u on any wagon-running gear, by simply p acing therebetween such a supporting-frame as will fit properly to s ace tiem apart.

T e shaft 11 of the beater-drum 12 may be rotated by any suitable means, and this shaft is caused to communicate rotatory movement to the aprondrivingshaft 17by the ratchetfeed-Inechanism now to be described.

A cam-wheel 1 is secured to one end of the shaft 11 as shown Fig. 1, and is of t form depicted. A lever 2 has its upper end pivoted on a stud 37 to the'upper end of.

fixed supporting-arm 3 attached to body 1 20. -The lower end of said lever 2 is adapted to movably rest upon the circumferential edge of said cam to be driven by the latter with a vibrating motion. rear end pivoted to the lower part of said lever 2, while its forward end is pivotally A link 13 has its Patented l rfllarcll 31, 1908.

connected to'a pawl 14 which is pivotally connected to. a supportingarm 15 whose lower end is pivoted. to the end of the shaft 17. A guard-pawl 9 is pivoted on a stud 8 extending from the bracket 10 the latter supporting the shaft 11 said pawl having stud 6 and a coiled spring 5 being connected between the lever 2- and said stud, the latter extending from the upper arm 7 of said pawl. Both pawls 9 and 14 are adapted to engage the teeth of the ratchet-wheel 16, the latter being fixedly mounted on the end of the apron-driving-shaft 17. A hand-lever 21 has its lower end pivoted on a stud 23 to the outside of the forward part of the box 20,

said lever movable within a rack-b ar 22, with whose teeth an outwardly bent YIOJQCUOII .on the lever is adapted to release-b y engage.

Said lever is provided with a bearing-ring 24 on an outwardly projecting stud the latter rotatably mounted in an orifice in said The forward lever and secured by a nut. end of the connecting-rod is is passed through said ring, and secured thereto by nuts; 25, the connection at this point thus ermittim the rin to swim as the lever moves forward or back. The connectingrod 19 has-its rear end slidnbly seated in a bearing-orifice in a lug BSextending from I I arm 3/ .rod between said pin and the inner face of the lever A short distance ahead of said lug the rod 19 is pierced and a pin 39 inserted to form an abutment for the coiled spring 18 seated about said said lug. The rod 19 is kept from lateral movement by being contained within a staple 1 secured to the The spring 18 forms a resilient compressible connection between the rod 19 and the lever 2, while the spring 5 tends to kee the pawl 9 in engagement with the teeth oft e ratchet-wheel16. When the lever2l is moved in one direction, the lever 2 is ad justed so small amount of throw, moving but onetooth of the ratchet-wheel 16 at a time, for slow speed of the apron, by means of the above described intermediate connections. When the lever 21 is thrown that the earn. 1 will ail'ord it but a forward the lever 2 is l with said aaaeee Having described my invention, what I claim as new, and desire to secure by Letters Patent, is 1 In a manure spreader, the combination with a box containing a movable endless longitudinal apron, a ed on a-rotatable shaft at the rear of said a )ron, a cam-wheel on said shaft, a driving- Sl htft for said apron; a ratchet-wheel on said apron-shaft, a pawl adapted to operatively engage the teeth of said ratchet-wheel, a lever pivotally supported by said box andhaving one end in o erative contact with-said camwheel, a linlz between said lever and said pawl, a raclr bar on said box, a hand-lever pivoted to said box and adapted to removablyengage any of the teeth of said rack ba'r, a connecting-rod having a swivel connection hand-lever and a resilient brought within the full radius of operation of 1 nection with said cam driven-lever, 'a guardthe wheel the distance of two or the pawl 14 is caused I said cam-driven-rod and the cam so as to cause the pawl 14 to drive pawl pivotally supported above and adaptmore teeth ed and by the action of the spring 5 aided by the wheel, and weight of the lever 2,

to engage with the teeth of said ratcheta spring connected between said guard-pawl to click back over more teeth, and by each adapted to ordinarily malntain the lattter impulse derived from the cam-wheel cause in en agement with the teeth of said ratcheta more rapid rotation of the shaft 17, with whee 1 consequent enhancement of the speed of the apron 27. Throwing the lever 21 in the opposite or rearward direction stops the apron by limiting the stroke of the pawl 14 to less than the length of one tooth of said ratchet wheel.
